EVALUATION BOARD FUNCTIONS AND REGISTERS
The
data-word to or to read a data-word from the DAC.
Example 1
Type 0x800 (the 12-bit midscale data value) in the Input Data box,
and click Write DAC. The output should then show a voltage of
−5 V, based on the following formula:
Example 2
Type 0xBFD (the three quarter scale data value) in the Input
Data box, and then click Write DAC. The output should then
show a voltage of −7.5 V, based on the following formula:
Click Read DAC. The Output Data indicator should then show
the 12-bit data value of the last data written to the part. Therefore,
for this example, the indicator would show a value of 0xBFD.
